- This is a generic X / pty problem, and not a result of any buffer
- size and not specific to MIPS.
-
- MIT worked on fixing this in X11 Release 5. Here is a summary of
- their comments from MIT bugs 3306 and 3673
-
- "xterm now feeds large pastes to the pty only as fast as it will
- accept data. Correct tty drivers will reject unwritable data with
- EWOULDBLOCK or EAGAIN. On such a system I have been able to paste
- /usr/dict/words (.2Mb) into an xterm running vi.
- After fixing xtem, I discovered that some O/S's claim the pty write
- succeeded when in fact they have dropped the data. I'm not going to
- publish the list of offenders here to avoid embarrasing the guilty,
- but don't blame me if you don't see any improvement."
-
- Although MIPS has not done an X11R5 release, they did attempt to fix
- the problemm by retrofitting the changes into X11R4 when they did the
- RISCwindows 4.10/4.11 release.
-
- Here are the MIPS bug fix comments (bug 4646)
-
- " Cut/paste works better. Even though the success rate for cutting
- large amount of text is not 100%, it's great improvment compare to
- previous releases already. Again, this is a generic problem, and it
- has been documentated in the "Known problems and limitations" section
- of the release notes.
- Fixed by grafting in an R5-based v_write() in charproc.c. "
-
- So, upgrade to RISCos 5 and RISCwindows 4.11 to get the fixes.
